Step 4. Locate the appropriate PCIe slot for the GPU.
Note: For server models with one processor, you can install one GPU in PCIe slot 1. For server
models with two processors, you can install up to two GPUs in PCIe slot 1 and PCIe slot 5, or up to
three GPUs in PCIe slots 1, 5 and 6. For more information, see "Specifications" on page 5.
Step 5. Align the GPU with the PCIe slot on the riser card. Then, carefully press the GPU straight into the
slot until it is securely seated. See "Install a PCIe adapter on the riser assembly" on page 168.
Step 6. If a GPU power cable is required, do the following:
a. Connect one end of the power cable to the GPU power connector on the system board.
b. Connect the other end of the power cable to the GPU.
c. Route the GPU power cable properly. See "GPU cabling routing" on page 35.
Step 7. Install the riser assembly with the GPU into the chassis.
